Guinea pigs are called guinea pigs due to a combination of their original price in 16th-century England and their physical resemblance to small pigs.
Unpacking the "Guinea"
The "guinea" part of their name is rooted in their historical cost. In 16th-century England, these fascinating creatures were a luxury item and could be purchased for one guinea each. A guinea was a gold coin, making them a significant purchase and indicating their value as exotic pets. While the term "guinea" might suggest an origin from the country of Guinea in West Africa, it actually refers to the value of the coin often minted from West African gold, not the animal's place of origin.
Deciphering the "Pig"
The "pig" in guinea pig is widely believed to come from their physical characteristics and behaviors that remind people of small pigs. This resemblance is not just a passing observation; it's a common perception that has influenced their names across various cultures and languages.
Several aspects contribute to this "pig-like" association:
- Compact Build: Guinea pigs have a stocky, robust body shape, similar to a miniature pig.
- Lack of a Distinct Neck: Their head appears to sit directly on their body, giving them a compact, barrel-like appearance.
- Vocalizations: They often make various sounds, including grunts, squeals, and rumbling noises, which can be likened to the sounds made by pigs.
- Eating Habits: Guinea pigs are known for their enthusiastic appetite, often munching away with vigor, a trait sometimes associated with pigs.
This perceived resemblance is further supported by the names guinea pigs are given in other languages, many of which incorporate a word for "pig" or "piglet" to describe them.
